Abstract: ABSTRACT          Disclosed is a cardiac pacing lead employing an elec-trode which has a novel geometry and which is provided with a coating of platinum black.  The electrode is generally hemispher-ical and is provided with grooving.  In its preferred embodiment, the electrode is provided with circular grooves and with tines which urge the electrode into contact with the endocardial wall, in a direction roughly perpendicular to the grooves.  The elec-trode may be constructed of platinum or of a conductive base metal provided with an external surface of platinum and is preferably coated over its external surface with a coating of platinum black.          The grooving of the electrode provides areas of small radius of curvature which contact the endocardial surface, resulting in lo-calized increases in current density at the edges of the grooves.          The hemispherical shape of the electrode maximizes the opportunity for contact between the groove edges and the endocardium.  In its preferred embodiment, the electrode displays extremely low polar-ization following the application of a stimulation pulse and thereby displays significantly enhanced ability to sense the nat-ural electrical activity of the heart.

Abstract: ABSTRACT OF THE DISCLOSURE          An optical arrangement for use in spectrometry uses a masking device which eliminates unwanted spectral regions prior to optically resolving the unmasked information.  The optical arrangement comprises an entrance slit to select incidence spectral energy from an energized source and a concave grating of relatively low dispersion to image the spectrum of the entrance slit onto a stationary mask which simultaneously selects spectral regions of the dispersed incident spectral energy.  The selected spectral regions are collimated and recombined and directed onto an Echelle grating to disperse with high resolution the selected spectral regions.  A concave mirror focuses the dispersed selected spectral regions into a focal plane of highly resolved spectral energy which can be detected to determine the spectral information coming from the source.  The optical arrangement is particularly well suited for use with narrow spectral bandwidth spectral information distributed over a large spectral range.  In spectroscopy, desired information very often occupies a tiny fraction of the total spectral information presented to a spectrometer.  With this optical arrangement, spectral information can be selected from a much broader band spectral information and collected with high resolution on a small curvilinear portion of the output focal plane.  The arrangement is particularly useful for absorption, light scattering or emission spectroscopy.  It provides a stable mechanical design making it less sensitive to vibration.  Manufacturing mechanical tolerances are also less restrictive.

Abstract: ABSTRACT OF THE DISCLOSURE        Method and apparatus for deriving a correction factor used in calculating corrected liquid (e.g., fuel) quantity of a tank having a probe capacitance which varies in accordance with the quantity of liquid contained within the tank.  The correction factor reduces sensing diode voltage drop errors and stray capacitance errors (affecting the capacitance of the probe) through use of a switchable high/low amplitude Lo-Z oscillator.          All oscillator outputs are "low" amplitude relative to the output amplitudes of conventional devices.  Signal processing is effected by inputting raw data (both reference and probe-sensed signals) to an analog-to-digital sampling circuit, which raw data are used for deriving the correction factor.  The correction factor is then applied to the raw data to determine a corrected liquid quantity indication.  Recalibration of the correction factor periodically permits automatic adaption to changing error magnitudes (i.e., changes in the deleterious effects of diode-voltage drop and/or stray capacitance).  Additionally, the relative "health" of the component elements of the tank unit is monitored by tracking changes occurring during recalibration of the correction factor.   Establishment of a correction factor outside a predetermined range might indicate faulty probe components or other such difficulties.  Numerous practical advantages and economies are obtained by the method and apparatus presently disclosed because of the enabled use of an oscillator with a relatively low voltage output (e.g., under 10 volts peak).

Abstract: INITIALIZATION APPARATUS FOR A DATA PROCESSING     SYSTEM WITH A PLURALITY OF INPUT/OUTPUT AND    STORAGE CONTROLLER CONNECTED TO A COMMON BUS                    Abstract A plurality of controllers are connected to a common bus in turn connected to a central processor.          Each of the controllers respectively serves as an interface between the central processor and at least one storage unit or input/output device.  In order for the controllers to distinguish between addresses, the addresses sent from the central processor contain identifier segments indicative of the controller to which the address is being sent.  Controllers in turn contain programmable comparison means for comparing the identifier segments in addresses to a stored controller identifier indicative of the controller.          Because the comparison means are programmable, controller identifiers have to be set up each time the system is turned on.  Consequently, the present invention provides such turn on or initialization means including a read-only initialization program stored in one of the storage units: the controller interfacing with this storage unit becomes a master controller; the master controller has apparatus which is selectively activated only during initialization for accepting all addresses irrespective of the identifier segment.  The other controllers have apparatus selectively activated only during ini-tialization for disabling the comparison means and such other controllers so that no addresses are accepted by the other controllers during the ini-tialization.  In other words, the comparison means in the master controller is completely bypassed during initialization whereby the read-only initialization program is accessed only through the master control-ler.

Each time a charge is accumulated on a scale, air is blown across the scale to discharge the scale.  The charges are delivered to a magazine. having a plurality of vertically stacked chambers, each chamber underlain by a movable gate, through which the charges are passed sequen-tially to be discharged at a fixed schedule from the lower most chamber.  Spikes mounted on the interior o e the drum are shaped to loosen portions of bales entering the drum, tear tufts from such portions, and finally deposit the tufts into an air stream passing through the drum to expel the tufts.  Between the drum and the picking chamber, the tufts are treated with an anti-static compound in a chamber through which the tufts fall while a mist of the compound is injected into the chamber.  Above the picking chamber, the tufts enter a deflection tower and are deflected to one side or the other of the picking chamber to concentrate the supply roll at one side of the picking chamber and filaments to each of two scales are drawn from opposite sides of the picking chamber.
